Firebase, a powerful backend-as-a-service platform, offers a seamless way to deploy and host your Flutter web applications. In this tutorial, we will guide you through the process of setting up a Firebase project, configuring your Flutter application, and deploying it to the cloud. By leveraging Firebase’s robust infrastructure and features, you can easily deploy and manage your Flutter web apps with minimal effort.
Getting Started
To begin, we need to ensure that we have the Flutter SDK installed on our system. The Flutter SDK is the backbone of any Flutter project, allowing us to create applications for various platforms.
If you don’t have Flutter SDK installed in your system, click here.
Next, we need to either create a new Flutter project or use an existing project. For a new Flutter project, run the following command and start preparing your app:
flutter create new_projectIf you have an existing Flutter app, navigate to the project directory in the command line.
Preparing the Flutter Web App
To prepare our Flutter firebase deployment, we need to ensure that the web framework preview is enabled in our Flutter project. This can be done by running the following command:
flutter config --enable-webOnce the web framework preview is enabled, we can build our Flutter web project. The flutter build web command compiles the Dart code into JavaScript, which is necessary for the web app to run in a browser.
flutter build webThis command generates a build web folder in the Flutter project directory. This folder contains the web application, including an HTML file that can be opened in a Chrome browser.
Setting Up Firebase
To deploy Flutter web to Firebase, we first need to create a Firebase project. Navigate to the Firebase console and click Create Project.
Install the Firebase CLI
Once the Firebase project is set up, we need to install the Firebase CLI. The Firebase CLI allows us to interact with our Firebase project from the command line. Run the following command to install the Firebase tools:
npm install -g firebase-toolsNext, we need to log in to Firebase. Run the firebase login command and follow the prompts to log in to your Google account.

With our Firebase project set up and our Flutter web app built, we can now deploy our app to Firebase.
First, we need to initialize Firebase hosting in our Flutter project directory. Run the firebase init command and select Hosting.
firebase initDuring the initialization process, we are asked to select the Firebase project to link to our Flutter web app. We also need to specify the public directory, which is the build web folder in our Flutter project to get firebase.json and .firebaserc files which have the details required to deploy the web application.
Finally, we can deploy Flutter web to Firebase by running the Firebase deploy command.
firebase deployOnce the deployment process is complete, we are provided with a hosting URL where our Flutter web app is live and accessible. And DEPLOYED!
Deploying a Flutter web app to Firebase is a straightforward process that involves preparing the Flutter web app, setting up a Firebase project, and deploying the app using the Firebase CLI. With this guide, we hope you are now equipped to deploy Flutter Web to Firebase hosting with ease. Keep Deploying amazing Flutter Web apps…🚀
Conclusion
By following the steps outlined in this tutorial, you have successfully deployed your Flutter web application to Firebase Hosting. Firebase provides a reliable and scalable platform for hosting your web apps, allowing you to focus on building exceptional user experiences. With Firebase’s integrated features and easy-to-use console, you can efficiently manage and monitor your deployed applications.
